favorite_borderWhy you'll love it

Fuel EX 9.9 is the single best choice for riders who want a versatile ripper for every kind of mountain biking, from fast XC races to burly technical terrain

RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control

It has all the latest tech that adds up to a great ride, like a 108-tooth Rapid Drive hub, Mino Link adjustable geometry, and Boost148/110 hub spacing

"Trek has elevated the Fuel EX's performance even further. This latest iteration feels just as quick on the climbs, but when it's time to descend, it's less phased by steep and technical trails than ever before. "

Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.

Control Freak Cable Management

The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.

Boost148/110

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
